Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68380, here are decompositions:

29 + 68351 = 68380
101 + 68279 = 68380
167 + 68213 = 68380
173 + 68207 = 68380
233 + 68147 = 68380
239 + 68141 = 68380
269 + 68111 = 68380
281 + 68099 = 68380

Showing the first eight; more decompositions exist.
